摘　　要：利用2009年裕民县5—7月气温、降水、云量等气象资料,分析了裕民县打瓜白粉病发病及流行期间所对应的气候条件,阐述了气象要素的变化在病菌浸染过程中产生的影响。结果表明:2009年5—7月裕民县气温较历年同期偏低,7月降水明显集中且中旬以连阴雨天气为主;播种期温度偏低及开花座果期降水分布集中、光照不足是导致2009年打瓜白粉病大流行的主要原因。Based on the temperature, precipitation and cloud cover data of Yumin County during Jun. to Jul. 2009, the corresponding climate conditions of powdery mildew period were analyzed and the influence of weather factor variations on pathogen transmission process was discussed. The results showed that： the temperature from May to Jul. of 2009 in Yumin is lower than the corresponding period of past years, and the precipitation is obviously concentrated in Jul., and overcast and rainy was the main weather in the mid-July; the lower temperature in seedtime of melon, rather concentrative precipitation and insufficient light in blossoming and fruiting period are main reasons for broad-scale powdery mildew prevalence of melon in 2009.
